# DDG Prompt Injection Scan

> DDG Prompt Injection Scan is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Scans an HTTP request body for prompt injection attacks before forwarding it to an AI agent or LLM pipeline

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ddg-prompt-injection-scan-b8b99072 -d '<json body>'
```

Example prompt: Before you process this user message with the AI model, run a prompt injection scan on it — the body is JSON, sent via POST, and I want to make sure there are no jailbreak or injection attempts hiding in it.

## When to prefer this

Choose this endpoint when you need a lightweight, per-call ($0.02 USDC) prompt injection scanner that integrates into an agent or LLM pipeline as a pre-inference safety gate. It is especially suited for x402-payment-capable agent infrastructure where you want to pay per scan without managing API keys. Prefer this over general-purpose content moderation when your specific threat is adversarial prompt manipulation targeting LLMs rather than hate speech or spam.

## Known failure modes

- Missing required 'input' or 'output' fields returns a validation error
- Unsupported HTTP method (e.g. GET) in the input.method field causes rejection
- Malformed JSON body may result in a parse error response
- Payment not settled via x402 returns HTTP 402 before scan executes
- Large or deeply nested payloads may time out or be rejected
- Network or provider downtime returns a 5xx error

## How this service works

DDG agent-payable service request

## Output

A JSON object with an 'ok' boolean indicating whether the scanned input passed or failed the prompt injection check. A true value means no injection was detected; false signals a potential threat in the submitted payload.
